Title: Two compartment cup for powdered sterilant reagent components
Inventor: SIEGEL NORMAN L
IPC: A61L2/24
Filed: 1992-08-17
Abstract: A front door (B) of a countertop decontamination unit is opened to gain access to a chamber  (10)  for receiving a cartridge (C) containing items to be sterilized and a chamber (12) for receiving a two compartment powdered anti-microbial agent carrying cup (D).  The cup includes an outer cup portion (60) and an inner cup portion (70) that have peripheral walls (62, 72) affixed together at flanges (64, 74) and abutting base walls (66, 76).  At least one of the base walls has a domed portion (68) constructed of plastic, whose plastic resiliency functions as a spring to urge the base walls continuously into engagement.   The inner and outer cup portions peripheral walls define an annular chamber (86) therebetween.  Preferably, the inner peripheral wall is generally conical to reinforce the outer cup base wall to prevent it from collapsing on impact with a cutting blade (14).    the inner wall has a longitudinally elongated recess  (80)  which  interacts with a  filling aperture (84)  surrounded by a flange portion (82).  The longitudinal recess and filling aperture are configured such that a filling tube (92) is selectively insertable through the filling aperture and along the recess for filling the annular compartment with a powdered reagent. A permeable sheet  (102)  is affixed to the second cup portion flange for sealing both compartments.

Title: Method for compensating for capacity overload in a spread spectrum communication system
Inventor: HALL SCOTT M
IPC: H04B7/005
Filed: 1992-10-05
Abstract: A method for compensating for capacity overload in a communication system by first determining the received signal power level at a base site (62) is described. The power level is compared with a threshold power level (63). If the received power level is greater than the threshold, the signal-to-noise ratio for the system is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscriber power will be reduced. The received signal power level at the base site will then return to the threshold level. Alternatively, a signal-to-noise ratio of a pilot signal can be determined (62) at the base. The signal-to-noise ratio is compared to a threshold signal-to-noise ratio (63). If the signal-to-noise ratio of the pilot is less than the threshold, the threshold level is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscribers are directed to reduce their power.
Patent CA-2102628-A1 (CA)
Title: Gene manipulation and expression using genomic elements
Inventor: SHERWIN STEPHEN
IPC: C12P21/00
Filed: 1992-05-05
Abstract: Expression of mammalian target genes is achieved by employing chromosomal target DNA, either native primary cells or YACs in a yeast host, where the YACs include a fragment of a mammalian chromosome, the fragment comprising the target gene. Employing homologous recombination, an amplifiable gene is integrated into the mammalian fragment at a site to allow for amplification. In the same step, or one or more steps, as desired, the mammalian gene and/or the transcriptional system may be modified by in vivo mutagenesis. The resulting construct from homologous recombination may then be transformed into a mammalian expression host and integrated into the host genome, either randomly or by homologous recombination. The amplifiable gene may then be amplified by an appropriate agent providing for multiple copies of the target gene and the expression host grown to provide for high yields of the desired wild-type or modified protein.

Title: Power stapler
Inventor: GOLICZ ROMAN M
IPC: B27F7/23
Filed: 1993-10-20
Abstract: POWER STAPLER               ABSTRACT OF THE DISCLOSURE  A power stapler having an improved clincher provides a stitcher head for driving formed staples into a stack of sheets.  A clincher box is positioned opposite the stitcher head.  Clinchers located in the clincher box pivot upwardly under the force of a moving clincher bar to deform ends of the staple to pass through the sheet stack.  The clincher bar or clinchers include a stop that limits retraction of the clinchers into the box.  Hence, as the staple is driven by the stitcher head through the sheets, the ends of the staple are brought into engagement with the clinchers and plastically deform into a substantially inwardly curled shape.  Following driving of the staple by the stitcher head, the clincher bar is actuated to rotate the clinchers upwardly toward the stack causing the curled tips of the staple to drive into the sheets. The clinchers can include grooves that are angled into alignment along parallel angled lines so that the ends of the staple pass each other and do not interfere with each other upon clinching.

IPC: A45D40/22
Filed: 1992-06-26
Abstract: A case for cosmetics including a cover and a base. The cover and base have end and peripheral walls which together define an interior compartment. An integrally formed latching device is located in the front portion of the case. The latching device comprises a push tab in the form of a tongue-like section of the base peripheral wall. The distal and intermediate portions of the push tab are separated from adjacent portions of the base peripheral wall by at least one slot which extends alongside the push tab to its proximal end. Coacting cam means associated with the push tab and with an adjacent portion of the cover produces a force biasing the front portion of the base and cover apart when the push tab is moved inwar-dly with the latch engaged. Interengagement means is in-tegrally formed on the cover and base peripheral walls to latch the cover to the base when the front portions of the base and cover are pressed together and unlatch when the front portions of the base and cover are forced apart.

Title: Quadrupole mass spectrometer
Inventor: FOLEY PAUL V
IPC: H01J49/42
Filed: 1994-04-13
Abstract: ABSTRACT OF THE INVENTION       A quadrupole mass spectrometer includes means for measuring total ion current having an electron repeller cage disposed about an electron source filament.   The electron repeller cage repels electrons emitted by the electron source filament, urging them away from both the repeller and the filament, while also attracting positive ions.  When the positive ions contact the electron repeller cage, a current is induced that is measured at the electron repeller cage.  The measured current represents total ion current transmitted through the spectrometer.  Thus, the need to include a total pressure measurement plate to measure total ion current is eliminated, and since the ion exposed surface area of the electron repeller cage is greater than the ion-exposed surface area of the total pressure measurement plate, the invention provides improved total pressure measurement sensitivity.

Title: Photoreceptor Comet Prevention Brush
Inventor: SASS DOUGLAS W
IPC: G03G21/00
Filed: 1994-05-27
Abstract: An apparatus for cleaning a charge retentive surface of a photoreceptor which includes a rotating brush for cleaning the charge retentive surface of a photoreceptor. A spring or other means is used to maintain constant, uniformly distributed contact between the charge retentive surface and the rotating cleaning member together. The use of one or more pressure rollers to maintain the cleaning brush next to the photoreceptor belt can prevent undesirable friction, heat and/or static charge buildup adjacent to the photoreceptor, and can prevent photoreceptor jamming and other malfunctions. The resulting self regulating cleaning brush contact improves photoreceptor cleaning effectiveness despite brush aging, bristle wear or set, or other factors effecting the radius of the cleaning brush or its relative positioning in the photoreceptor cleaning assembly. The present invention results in the uniform distribution of the contact pressure on the photoreceptor, which may monitored and/or be controlled. A cleaning bar for dislodging debris that might otherwise remain attached to the rotating cleaning brush may also be biased towards and movable relative to the rotating brush.
